Abstract (en)
A composite cylinder assembly (300) may comprise a tube liner (302) including a first domed portion (304) defining a first liner neck (306), a second domed portion (308) defining a second liner neck (310), and a cylindrical wall (312). The cylinder assembly (300) may comprise at least one port. The port (401, 403) may comprise an outer diameter configured to fit into an inner diameter of a liner neck and a lip (404, 407) including an outer diameter that is greater than the inner diameter of the liner neck. The port may comprise a swage recess (406, 409) having an outer diameter that is less than the inner diameter of the liner neck and may be configured to press-fit into the liner neck. The lip may be configured to provide a surface area to weld the port to the liner neck. The swage recess may be configured to provide an area to swage the liner neck to the port.
